Definition that contains phase i
- sol a colloid that has a continuous liquid phase in which a solid is suspended in a liquid
- medusa one of two forms that coelenterates take: it is the free-swimming sexual phase in the life cycle of a coelenterate; in this phase it has a gelatinous umbrella-shaped body and tentacles
- wavelength the distance (measured in the direction of propagation) between two points in the same phase in consecutive cycles of a wave
- incubation (pathology) the phase in the development of an infection between the time a pathogen enters the body and the time the first symptoms appear
- medusan one of two forms that coelenterates take: it is the free-swimming sexual phase in the life cycle of a coelenterate; in this phase it has a gelatinous umbrella-shaped body and tentacles
- hydrozoa coelenterates typically having alternation of generations; hydroid phase is usually colonial giving rise to the medusoid phase by budding: hydras and jellyfishes
- anthozoa a large class of sedentary marine coelenterates that includes sea anemones and corals; the medusoid phase is entirely suppressed
- phase ii a clinical trial on more persons than in phase I; intended to evaluate the efficacy of a treatment for the condition it is intended to treat; possible side effects are monitored
- sporophyte the spore-producing individual or phase in the life cycle of a plant having alternation of generations
- anthozoan sessile marine coelenterates including solitary and colonial polyps; the medusoid phase is entirely suppressed
